【Example】

 Next, the present invention will be described with reference to the drawings. 1 is a perspective view of a vehicle seat according to an embodiment of the present invention, and FIG. 2 is a central transverse plane of a recess 11 for fitting a fragrance storage case 20 formed in a seat back 10 of FIG. 3 and 4 are rear perspective views of the fragrance storage case 20. The fragrance storage case 20 is formed in a shape that matches the shape of the recess 11, and a pair of surface adhesive pressure-sensitive tapes 21 provided on both the back surface of the fragrance storage case 20 and the bottom surface of the recess 11. , 12 are detachably fitted and mounted in the seat back 10. As shown in FIG. 3, the surface adhesive tape 21 provided on the back surface of the air freshener storage case 20 is separately attached to the upper and lower two tapes, and the air freshener is placed in the middle of the two air adhesive tapes 21. The charging port is opened, and the back cover 22 is provided so that the charging port can be covered except when the fragrance is charged.

FIG. 4 is a central transverse plan view of the fragrance storage case 20 of FIG. The outer surface of the fragrance storage case 20 that is not in contact with the recess 11 of the seat back 10 and the side surface are one of the surfaces of the seat when the fragrance storage case 20 is fitted into the recess 11 of the seat back 10. The case cover 23 is made of the same material as the seat cover so as not to impair the sensation, and the inner container 25 containing the fragrance 24 is covered by the case cover 23. The front surface 25a of the inner container 25 is provided with a hole 26 for communicating the inner portion of the inner container 25 with the outside, and the sheet 26 is formed by penetrating substantially the central portion of the front surface 25a of the inner container 25. A movable member 27 that is movable in the direction perpendicular to the back surface is provided.

The movable member 27 will be described in more detail. The movable member 27 includes a rod portion 27a penetrating the inner container 25 and a plate-like member integrally formed at one end of the rod portion 27a and abutting on the case cover 23. The rod portion between the outside of the inner container 25 and the plate-like portion 27b is provided with a portion 27b and a lid portion 27c that is integrally formed at the other end of the rod portion 27a and that covers the hole 26 bored in the inner container 25. The plate-shaped portion 27b is pressed against the case cover 23 by the compression spring 28 fitted in the 27a. A seat pad 29 is filled around the movable member 27 between the front surface 25a of the inner container 25 and the case cover 23 so as not to impair the cushioning property. Further, an fragrance input port 30 for adding or changing the fragrance 24 is provided on the back surface of the inner container 25, and the back lid 22 uses the torsion spring 31 for the fragrance input port 30. It is attached so as to be biased in the closing direction. When the aromatic agent 24 is charged, the back cover 22 may be pushed into the inner container 25 and charged.

When the fragrance storage case 20 thus formed is fitted into the recess 11 of the seat back 10 and attached, the hole 26 of the inner container 25 is provided with a cover portion of the movable member when a person is not seated. Although it is closed by 27c, when a person sits down, the plate-like portion 27b is pressed through the case cover 23 to move the movable member 27 toward the inside of the inner container 25, and at the same time, the lid portion 27c is removed from the hole 26. The holes 26 are opened apart and aroma is generated from the holes 26.

FIG. 5 is a cross-sectional plan view corresponding to FIG. 4, showing another embodiment of the vehicle fragrance storage case according to the present invention. The inner container 41 is covered with a case cover 42 made of the same material as the seat cover. An annular air port 43 is bored in the front surface 41a of the inner container 41, and an annular bellows 44 is airtightly attached to the air port 43. The bellows 44 is in contact with the case cover 42 and expands and contracts by pressing the case cover 42 so that the air in the bellows 44 flows into or out of the inner container 41 through the air port 43. It has become. Further, a hole 45 is provided in the front side surface 41a of the inner container 41 near the center of the annular bellows 44, and one end edge portion 45a of the hole 45 is provided with an air pressure inside the inner container 41. An open valve 46 is attached that opens outwardly when it rises and connects the inside and the outside of the inner container 41.

When the fragrance storage case 40 thus formed is fitted into the recess 11 of the seat back 10 and attached, when the person is not seated, the bellows 44 is expanded and the opening valve 46 is closed. When a person sits down, the bellows 44 is pressed through the case cover 42 and contracts, and the air in the bellows 44 flows out into the inner container 41, so that the inner container 41 is temporarily pressurized. Therefore, the open valve 46 is opened and the aroma is released to the outside. Then, as the internal pressure of the inner container 41 decreases, the opening valve 46 gradually closes. After that, when the pressure on the fragrance storage case 40 by the seated person is released, the bellows 44 is restored to the extending direction, and at the same time, air enters the inside of the inner container 41 through the gap between the inner containers 41 and the fragrance storage case. 40 returns to the original state. It should be noted that if a valve element that opens only in the direction in which air enters the inner container 41 is provided in a portion of the inner container 41, the restoration of the bellows can be performed smoothly.
